Purchase route
Panda Podium currently lists the exact BIGROCK Sohtea frameset SKU BIGROCK-01-SOHTEA with a foreign-retailer route; mainland China stock, delivery, duties and checkout are unverified.
Frame weight basis
Frame only, excluding alloy parts and accessories; XXS 730 g, XS 750 g, S 780 g, M 810 g, L 830 g and XL 860 g, each ±5%; XXL unpublished. Video field report: China Cycling weighed a size-XS Team Edition frame at 673 g with derailleur hanger and bottle-cage bolts.
Stiffness evidence
Independent exact-model long-term review describes lateral stiffness and responsive out-of-saddle handling after building three Sohtea bikes; qualitative ride evidence, not an instrumented frame-deflection test
Current exact specialist-retailer offer, foreign add-to-cart route and per-size weights are attributable. The CNY amount is a reference conversion, mainland China checkout is unverified, and stiffness evidence remains qualitative. The current BIGROCK Japan product list did not show Sohtea, which does not establish discontinuation; retailer-gallery reuse rights remain undocumented.

Takeaways
Price at publication1:45In October 2024 the regular frameset with fork, 27.2 mm seatpost and fittings was just under US$1,200 and the Team Edition about US$1,700 at the presenter's own store.
Measured2:27The retailer-presenter reports his XS Team Edition frame at about 680 g painted with hardware, and a colleague's XXS regular-edition frame at about 760 g; the regular lay-up is said to be 100–150 g heavier.
Measured3:21His XS Team Edition climbing build with L-Twoo wireless, ~925 g prototype wheels and 28 mm tires weighed 5.94 kg with pedals, cages and mount; a budget regular-edition build was about 7.4 kg.
Ride impression10:18Very stiff and lively out of the saddle on 15–25% climbs, calm on descents but twitchy with very light wheels, and noticeably less aero above 40 km/h.
Finish and faults11:39Three frames built at his shop all had faced brake mounts and clean threads; one survived airline travel in a cardboard box without damage.
Support12:29Warns of an AliExpress listing at about US$488 whose buyer reported the seller vanished; buy from known sellers.
Fit check13:59With 28 mm tires measuring about 29–30 mm on a wide rim, a 4 mm hex key passed all round, so he expects 32 mm tires to fit despite the 30 mm rating; small sizes have some toe overlap.

A first look at BIGROCK's road frame, regular and Team Edition, built up at Panda Podium.
China Cycling · 2024-03-11. China Cycling's presenter also runs Panda Podium, which sells BIGROCK frames. The video does not name the model, but shows the same XXS regular and XS Team Edition frames as his later Sohtea long-term review.Disclosure basis.
Takeaways
Fit check1:44The frame is not a copied Aethos: the lowered seat tube leaves more exposed seatpost on small sizes, which he says helps comfort for short riders.
Finish and faults3:37His mechanic built an XXS without the usual sanding or chasing, and the clear-coated carbon showed no flaws; the frame comes with several headset covers for different routing options.
Ride impression5:11Even in XXS, too small for him, it tracked and turned in well on a local descent, unlike most extra-small frames he has ridden.
Measured6:48His size-XS Team Edition frame, claimed to use Mitsubishi carbon equivalent to T1100, weighed 673 g with derailleur hanger and bottle-cage bolts and a T47 shell.
